Allooimmunosensitization in left ventricular assist device recipients and impact on post-transplantation outcome
 Urban, Marián ; Netuka, Ivan (advisor) ; Ošťádal, Petr (referee) ; Mrázek, František (referee)
Background: In recent years mechanical circulatory assist devices became an established option in bridging patients with refractory heart failure to heart transplantation. One of the alleged limitations of mechanical devices is a high degree of antibody production with possible deleterious effect on subsequent heart transplantation outcome. Aim: The main goal of this study is to assess the role of antibodies on the outcome of surgical treatment of patients with end- stage heart failure. Method: Firstly, we present a literature review on the current state of knowledge of possible immunologic mechanisms involved in antibody production in left ventricular assist device (LVAD) recipients, new methods of antibody detection, desensitization strategies and overview of published evidence assessing the impact of sensitization on post-transplantation outcome. In the experimental part of our study we prospectively evaluated the presence of anti-Angiotensin II Type 1 Receptor (AT1R) antibodies in 83 Heart Mate II (HMII) recipients who were implanted at our institution between 2008 and 2012 and survived the first 60 days. On-device survival and device malfunction, major infection, major bleeding and neurologic dysfunction were compared between antibody positive and antibody negative recipients. Out of a total...
